About the challenge

Date: Saturday 20 September 2025
Location: Hyde Park, London
Event distance: 2 miles
Fundraising target: £350 (registration fee £25)

Release your inner dolphin and join Team WWF to take on the two-mile distance at Swim Serpentine. The popular Swim Serpentine event takes in half a lap of the world-famous lake in London’s Hyde Park. It's the perfect option if you’re looking to complete an achievable but memorable swim at your own pace or making the transition from the pool to open water.

Entries for the two-mile distance on Saturday 20 September 2025 are now open. And by taking part in support of WWF, you’ll be helping to power our vital conservation projects across the UK and around the world. What’s more, all finishers will receive a medal after their swim, as well as a souvenir swim hat to wear on the day!

Got your own place or want to take on one of the other distances? We'd love you to join Team WWF with your own place in the event. There is no minimum fundraising target and you'll receive the same high level of support as our charity place swimmers! 

ACCESSIBILITY

The organiser of this event supports participants with a range of disabilities at Swim Serpentine.

They've included a number of measures to help swimmers who require assistance to feel safe and confident at the event, including:

  • a ramped entrance into and exit out of the Serpentine
  • assistance with entering and exiting the water
  • accessible toilets and changing facilities

Please note that you do not need to enter a specific wave at the event to receive support. If you have any further questions about the disability support available at this event, or if you need any additional assistance, please get in touch with the organisers directly by emailing disability@londonmarathonevents.co.uk.
